roAmne APPARATUS.

Dehue, in-the county of Logan and State of lVesLVirginia, have invented certain new and .useful Improvements in Loading Apparatus, of which the following is a speci- 'fication.

The present invention relates to improve-- ments in loading apparatus and especially to that type designed to beused where the 7 head room is more or less restricted.

More specifically, the primary object of myinvention is to provide a practical device which is simple in construction but of adequate strength or power to handle coal or ore within mine levels, tunnelsor similar places, and by means of which the removal of large quantities of said material may be' greatly facilitated. But I desire it to be understood that the utility ofmy invention is- 1 not confined to 'such'mi ne operations alone since the apparatus is capable "of carrying out its functions in connection with other like operations, asin road work, unloading vessels, etc.

Another object in View is to provide an apparatus having novelmeans for obtaining variability of its radius, that is means whereby the horizontal distance from the axis of rotation to the point at which the load is suspended may be varied and that bymeans separate from the means employed for hoisting'the load.

A still further object is to provide a machine with a horizontally swinging boom to Lwhich the loading device or shovel. is directly connected so as to-obtain the maximum efiiciency of thrust without likelihood of damage, and means for shifting the shovel from. loading tounloading position and vice versa indeperidentof the boom swinging operation.

These and siichother objects as may hereinafter appear are attained by the novel con- 1 .ened state;

an N Fig. 8 is a rear elevation of the shovel. Throughout the following detail description and on the several figures of the draw ings, similar parts are referred to by like reference characters. I

As indicated above, the apparatus used in the mining of coal and ore has very restricted limits in the vertical and it therefore becomes impracticable to employ machines embodying verticallyoperated lifting booms or 1bs. The range of operation in the horizontal evenis not ordinarily very extensive so that m designing my invention it-has been my aim to arrange its structural.

parts so that it will have a fair radius of action subject to certain extension to elimi nate unnecessarily frequentshifting ofthe machine.

It should be furthermore understood that the materlal which ishandled by this ma- {chine is ordinarily of a loose character, or

is preferably loosened previous to being worked upon by the apparatus; however, it

is so constructed as to be able to actually Specification of Letters Patent. I Pate ted Au 30 19 1 5 Application filed 'November 3, 1919. Serial No. 335,531.

excavate the material if it is not in its loos- In the preferred 2 into position for loading the material, as

. will be hereinafter described. Upoii the forward end of the truck 1 is mounted a turntable, consisting of channeled track 3 which'carries a boom supporting frame 4- of special construction; At the. forward and rearward ends of this support are disposed a plurality of anti-friction rollers 5 which operate upon the circular track 3, and at thfl" embodiment, the mecha- 'msm is mounted upon the truck 1 which ope'rates or moves upon the usual mine track by means of which the boom is actuated forwardly and rearwardly, or more strictly speaking longitudinally, to extend its radius of action. -The pinions are carried by a. ShOItdIIVG shaft mounted in bearing sup-' ports 10 supported upon the frame it-and said shaft also carries the worm gear 11 whichis'driven by the worm 12 and the motor 13. This motor is also mounted upon :the support 4 and its weight tends to coun-.

terbalance the Weight upon the outer endof the boom so as to el minate unnecessary strain-upon the channeled track.

A special feature of this apparatus resides in the mounting of the bucket orshovel upon the outer end of the boom. It will be observed that the bucket 14 is pivotally Suspended upon the shaft 15 mounted in suitable bearing brackets 15 upon a side member 7 of the boom frame so that the shovel in operation swings transversely of the boom. At its rear end this shovel is provided With .a discharge gate or door 16 having a suitable lock 17 for holding the door inclose'd position until the discharge of thec'ontents is desired. It is to be understood thatthis locking mechanism for the door may be manually or; automatically operated, it being immaterial whichso far as this'invention is concerned. At its forward or cutting edge-the shovel is preferably provided with suitable teeth18 to facilitate thoroughly loosened.

The shovel is provided with power hoistthe loading of the material if it is not ingmechanism for raising and lowering the same on its pivot connection in loading and discharging its contents. For this purpose I connect to the forward end at each side a cable 19, 19 each of which passes over an overhanging sheave 20 and attaches to the common connector 21to which the cable 22' from the lifting drum is connected. This cable 22 passes over the sheave 23 mounted upon the boom support 4 adjacent to the axis of the support which consists of a hollow hub 24 suitably provided with friction bearings25, the cable passing downward through the said hub 24 and about a lower sheave 23, then rearwardly to the lifting drum 26 upon the rear portion of the platform 1. The drum is actuated through the shafts 27 and .28 by the motor 29 carried I upon said platform.

about its pivot thereby latformextremities if desired.-

At this point it is important toobserve that the side member of the boom to which the shovel 14 is connected is provided with depending stop arm 7 which limit the downward movement of the shovel and sustain the thrust imparted to'the shovel in theloading of the material thereupon. These arms are so arranged as not to interfere with the discharge gate for the shovel hereinbefore referred to. I

The boom isfswung about the axis by mechanism which is now to be specifically set forth. About the periphery of the channel track 3 are arranged a series of friction rollers 30 anda cable from thedrum 31 on the platform 1 extends about each side of this track to a point in front of the turn table where each is connected to the swinging arm or bracket 32extending from the boom support. The head and .tail lines or cables just-referred to, designated 33, 33 are operated through the instrumentality of the main -mot-or 3 4=,-a clutch lever 35 being provided for the control of this operation. This motor also controls the movement'of the truck through the t'ransverseshaft 36 which drives the truck through the chain 'connection 37," itbeing-contemplated that certain clutch' connections for this purpose are employed to obtain the proper actuation of the drum swinging elements and the propelling means, which is a purelyconventional mechanical arrangement and need not be. more specifically indicated. At one side-of the platform is also located the cablc 'drum 38,

operatedthrough the propelling mechanism so as to properly Wind and unwind the cur rent cables for the motor instrumentalities, the motors themselves being controlled by means of the conventional motor controls 39 arranged at the rear end of the platform 1,

In the operation of the device it will be understood that the loading apparatus hereinbefore described is-run into the mine upon theusu'al track 2, as liereinbefore indicated, to the point where the material for loading is located. The shovel is then lowered upon its pivotal connection and the boom swung loading the shovel with the material to be handled. The 'shovel v is then hoisted upon its pivot connection and the boom swung 'in the opposite direction to the point of discharge, which is, most clearly shown in, Fig. 2 of thedraWings, as upon a conveyer 40 arranged .at one side of the track which conveyer passes the material. rearwarclly in the usual conventional manner; The contents. of'course, are discharged from the bucket by tripping the v 1 locking mechanism 17 and the shovel is then Duragain loaded in a similar manner.

'ing the loading operation the usual jacks {i1 may be employed to support the he loading of" the inaterial continues. until that which is within the radius of swing ,of the boom is disposed of whereupon the boom is moved forwardly by the motor 13 and its rack and pinion connection to the boom, giving a greater radius of swing to the boom, This continues, in the load ing operatio until it. becomes necessary to advance the truck, which is accomplished by means of the propelling motor in the manner 'hereinbefore indicated. 1

In conclusion it will be observed that a very rigid and compact apparatus is pro- "vided by the foregoing arrangement and said apparatus is capable of carrying out its function in places where the head room' is very low, because the, bucket is operated within-the planes below the boom. The

direct connection of the bucket to the boom permits of considerable power being-exerted against the same when it is being loaded or pushed into the .material Which is to be handled. It is to be understood, of course,

that slight modifications may readilybe made in -the details of construction without 'departing'from the spirit of the invention and within the scope of the claims hereto appended.
